EYEeLAss-MouN'rmG;

Toall whom it may concern:

Be' it known that I, Lno F. Arm,- of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglass- Moun't'ings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being, had to the accompanying drawings, forming a part of this specification, and to the reference-nu 'merals marked thereon.

The present invention relates to eyeglass mountings and it has for an object to make provision permitting the distance between the centers of the lenses to be adjusted and constructed and arranged so that a very small pupilary distance may be obtained.

'To' this and other ends the invention consists in certain improvements and combina tions of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a front view of a mounting constructed in accordance with this invention with one of the nose guards'removed; Fig. 2 is a top view of the same mounting with the same guard removed; Fig. 3 is a vertical-central section through the mounting, and Fig. 4 is a detail perspective view of one end of the support.

In the embodiment herein shown the lenses A are connected by a support which may comprise a bridging or arch'ed portion 1 having its ends 2 lying, in this instance,

in the plane of the lenses. Connected to these ends 2 at points in vertical planes with said ends transverse to the plane of the lenses are adjustable 'or pliab e portions 8 which, in this instance, are each in the form of a forwardly opening and horizontally arranged loop, the forward end of the inner "arm of which merges into an end 2 of the bridging portion 1 and the forward end of the outer arm. is secured to the rear 0r posterior portion of the lens attaching device which. in this instance, embodies parallel arms 4 connected by a lens bearing portion 5 and having the lenses A secured between the parallel portions by a screw or other fastener 6; The support also carries bearings for the nose guards and. these hearings are preferably vertically arranged and lo- Specificatioi1 of Letters Patent.

the loops 3 so that the distance between the I ends'2 of the bridging portion. and thelens attaching devices may be reduced to a minimum, and also that the mounting when viewed from the front will not be conspicuous; In the present instance the bridging portion has extended outwardly from the ends thereof-between the arms of the loops, horizontal brackets or seats 7 carrying vertical hearings or pivot pins 8 preferably formed, with heads 9 at their free WVith this arrangement, the inner ends of ends. f

the loops 3 connect with the bridging por tibn and the inner sides of the lens attaching devices and the loops are thereby hidden by the brackets 7.

Cotiperat-ing with the bearings 8 I support are the nose guards which swin in a plane transverse to the planefof the lenses and may be of any suitable construction. Preferably each embodies a lever. 10

mounted to swin over the loo h provided with a vertical laterally i bearing at a point between its ends to cooperate with a bearing'S andhaving a filiger piece or operating portion 11 at its for- Ward end and a seat 12 in rear ofits boa i for an arm 13 bent outwardly from the rear edge of the nose engaging member 14, which preferably has upper and lower nose engaging surfaces. The arms of each pliable loop 3 by lying in the same plane and in rear of the ends of the bridging portion provide surfaces which will cooperate with the guard levers and prevent thewabbling of the latter, while a stop or shoulder 10 on the lever cooperates with the bridging porti'on to limit the inward movement of the nose ongaging member 14.

The guards may be positioned in any suitable manner but it is preferred to employ a spring carried with each guard and comprising a true spiral coil 15 having its axis upright and located in rear of the pliable or adjustable loop 3, an arm 16 being extended forwardly from one end of the coil and cooperating with a depending hook or projection 17 on the support to position a guard and hold the laterally openin bearing thereof in engagement with the bearing 9. This arrangement permits the guard and the ent pupil ary be adjusted very the lenses in ment with and joined integrally to the other spring to be removed quickly for the purpose of repair, for adjusting the mounting to different noses, or for any other purpose.

the latter, the operating orthus separating the nose engaging members 14: and placing the springs under tension'sothat when the finger pieces 11 -are released the springs move the nose engaging 'members .14; toward each other. For obtainingdifierdistances the portions?) are bent by. pliers or by' hand until the proper positions of the lenses are obta ned.

IEyeglass mountings constructed in accordance 'with this invention in additionto perniitting the adjustment for difierent pupildistances, enable a minimum pupilarydistance to be obtained as the pliable portions' proceed directly from the ends of the bridging ortion on the inner sides of the pivots so t at the lens attaching devices may close to the pivots. Further the loops which efiect this result are so located as to be inconspicuous when viewed from the front of the mounting.

I claim as myinvention: I 1. In an eyeglass mounting, a support for the lenses embodying a bridging portion having an end' turned in a directiontransversely of the plane of the lenses, an adjust-- able loop having one arm arranged in substantial alinement with the bridge end and .connected thereto,- a lens attaching'device carried by the other arm of the loop and a nose guard bearing carried by the bridging portion and located between 'the vertical 1 planes of the respective arms.

a support for the lenses embodying a bridging portion, having an end turned in a direction transversely of the plane of the lenses, a pliable loop having one end arranged in substantial alinement with the bridge arm and connected thereto, a lens attaching device carried by the other arm of the pliable loop and a nose guard bearing carried by the bridging portion and located between the arms so that the lens attaching device is adjustable relatively thereto. v r
